Sand for Students Fieldwork 1 (Hokkaido, JPN)

The first Sand for Students fieldwork program was carried out in Hokkaido, Japan. The deep-sea drilling vessel Chikyu, which was completed in July, 2005, has been undergoing repeated drilling tests in preparation for scientific drilling expeditions that the Integrated Ocean Drilling Program (IODP) will carry out from 2007 on. In the summer of 2006, the Chikyu was scheduled to do test drilling off the Shimokita Peninsula, during which it would collect geological samples (cores) from beneath the seafloor. For that work, the Hokkaido and Tohoku areas of Japan were a focus of interest, since they are the sedimentary source regionsthat had provided the sediments now under the sea. To collect sand for analysis, Sand for Students fieldwork was thus carried out at the Mukawa River in Hokkaido.

During the fieldwork


The start:Introduction of regional geology


Collecting for heavy minerals by panning


Swirling the pan in the water so that the light minerals fly out, to collect the heavy minerals effectively.
